2 MAC addresses for 1 IP address and load balancing across etherchannel?

Istvan kelemen

Hello,

 

I have seen an interesting article, the guy was able to copy by 450 MB/sec using a quad port NIC and a single TCP connection.

 

The server does per packet, per NIC, round-robin load balancing.

With a single switch in the middle, it should not be an issue, since the switch forwards packet based on dest mac address, right?

 

What about 2 switches in the middle? Is that enough to have an etherchannel with 4 ports between them, and the load balancing mechanism set to src-dest mac?

 

 

What happens if there is a L3 ethercannel between the switches? src-mac address should work, correct?

 

 

Thanks,

István

Hi,

src-mac should work fine.  Remember that port-channel load balancing method is configured globally on the small switches like 3560, 3750, etc.. and not per port-channel group.  Another word, you can only have one type of load balancing for the entire switch and not multiple.
